Lesson Study

• The opportunity to be able to reflect and refine.
• Putting a lesson in a different format from our usual manner

Technology

• Learning from peers about the technology
• Increased confidence and competence with the technology in students and teachers

Student Learning

  • Ability to quickly assess and give immediate feedback
  • Students have opportunity to comment on and support other students thought process

Collaboration

  • Merging several ideas from different perspectives
  • Reflecting, then giving and receiving feedback in a safe atmosphere

Unexpected Learning

  • How much Modelled and Shared Teaching needs to be clearly defined
  • Keeping the purpose clearly defined can be tricky

Hi,

We had a great brainstrom session on Friday! Thanks Devon for your great ideas using the Notebook software and Mette for completing the lesson plan outline. I found some of the things that we were looking for in the Guide to Effective Instruction re: Anchor Chart for Adding and also Instructional Strategies.

I e-mailed the details to you. Please let me know what you think!!

Oh yes, there is also the E-Workshop Website that has a video that we may wish to include. It is at http://www.eworkshop.on.ca/edu/core.cfm (Numeracy, Operational Sense)


Please find possible report card comments, an observation checklist and word problems below:
Please feel free to make changes!

.

  • demonstrates a general understanding of adding 2 digit numbers with regrouping, by selecting and applying some appropriate problem-solving strategies and by using pictures, words, and/or diagrams to clearly describe addition concepts, reasoning, and processes of investigation.
Level 4
  • demonstrates a thorough understanding of adding 2 digit numbers with
regrouping, by selecting and applying the most appropriate problem-solving strategies and by using pictures, words, and/or diagrams to clearly and precisely describe addition concepts, reasoning, and processes of investigation.

Grade 2 Math
2-Digit Addition with Regrouping
Place Value Charts

Lesson Focus
2-digit addition with regrouping on a Place Value Chart

Teaching Strategy
Modeling problem solving - teacher think aloud
Shared problem solving - students solving problems with teacher
- students solving problems together
- use of manipulatives such as Place Value Chart and Base Ten Blocks


Rationale

Students have been learning strategies for addition in previous lessons. As a continuation of becoming numerically competent, they will need to learn to regroup when using larger numbers.

Assessment

Observing the students communicating/verbalizing addition with regrouping using the Place Value Chart strategy.

Prior Knowledge
Prior to this lesson students need to:

• have effective counting strategies
• be able to combine and partition numbers using single and double digit numbers
• understand place value
• have learned several addition strategies (


Curriculum Expectations

Math: Number Sense and Numeration
• solve problems involving the addition two-digit whole numbers, using a variety of strategies. (Overall) (2m10)
• solve problems involving the addition of two-digit numbers, with regrouping, using concrete materials (e.g., base ten materials, counters), student-generated algorithms, and standard algorithms;(Specific) (2m26)

Materials & Preparation
• Smartboard, projector, and laptop
• Create teacher-student generated anchor charts from previous lessons on “click and reveal” squares in Notebook software for the Smartboard.
• Have two word problems set up in Notebook software that have numbers and phrases that represent key information in a separate text box so that you can clone it and drag it down to the bottom of the screen.
• Create Place Value Chart in Notebook software for the Smartboard. -Guide to Effective Instruction (p.27 &28) suggest the following (should we begin here or continue with our original plan?
• providing meaningful experiences with number lines and hundreds chartsexperiences in which they use movement and patterns on the lines andcharts to represent addition
• Base-ten blocks for students to manipulate during student pairing
• Ten word problem cards for student pairings. Word problems should be differentiated to reflect student needs.

This is the Notebook file for the lesson.

Differentiation
Provide word problems at manageable reading levels of the pairs.
Would you like to word problems altered?

    Instruction
    MODELLED/SHARED LESSON

    Before:
    • Activate prior knowledge by engaging students in a discussion about addition strategies they have already learned.
    • Have teacher-student generated anchor charts from previous lessons on “click and reveal” squares in Notebook software projected on the Smartboard.

    During:
    • Modeled focus:
    • Show the students the “Pizza Problem” on the Smartboard.
    • Model how to solve the problem on the Smartboard using re-grouping. To show this on the Smartboard, have numbers and phrases that represent key information in a separate text box so that you can clone it and drag it down to the bottom of the screen. Model how to select key information to include in the Place Value Chart by dragging it from the word problem and then creating the numbers in the Place Value Chart.
    •The key information to be cloned is
    • Work on the problem by first representing the numbers in a Place Value Chart.
    • On the Smartboard, model how to take the ones, count them and make them tens and ones.
    • Model how to add the two numbers using a Place Value Chart to regroup.

    Shared focus:
    • Using a second similar word problem, share the problem solving strategy of regrouping using a Place Value Chart with the students.
    • Invite students up to the Smartboard to do aspects of working on the problem
    • Invite students to also identify the key information that needs to be put into the Place Value Chart

    Student Pairing
    • Students will work in pairs to solve other word problems.
    • Circulate and record anecdotal observations as students work through the activity. Pay particular attention to how the students are regrouping. Have they identified the key information needed to solve the problem? Are they using the Place Value Chart properly? Conference with students who require assistance.

    After
    • Bring the students back together and discuss what was easy, and what was difficult for them.
    • If any problems arose, ask how they solved their problem to arrive at the correct answer.

Hi Mette,

What a great lesson plan! Thank you for all of your hard work.
I made some possisble suggestion in red print and also changed some of my work to hopefully better reflect The Lesson Plan.

I had difficulty adding pictures to the word problem cards in the Wiki, but if the problems are alright I can make them in another program.
Have we included a graphic organizer, or is the Place Value Chart our graphic organizer?

Please feel free to make any comments or changes.

Just found the rubric below that could be used at a later stage:
